The aqueduct was constructed to afford a maximum dis-charge of 72,000,000 United States gallons every twenty-four hours, and it. was thought utterly impossible that such a supply would be required for generations to come. But within thirty years even this amount was found inadequate; and by permitting the water to rise in the aqueduct to within twelve and one-half inches of the crown of the arch — thirty-two inches higher than had been originally in-tended— a daily supply of 05,000,000 gallons was forced, which, in turn, was found so far from meeting requirements that two new sup-1 This was the old Forty-second Street reservoir, ions since disused, whoso site is to be occupied by the New York Public Library.

In this chapter we have undertaken to follow the successive events of principal importance from the close of the Revolution to the com-pletion of the Croton Aqueduct. A glance at. various particulars and aspects of incidental consequence and interest during this period of sixty years is necessary before continuing our narrative. We have seen that the Milages of Sing Sing and Peekskill were incorporated, respectively, in 1813 and 1827.
